An archive of my engineering projects, spanning from low-level embedded hardware and analog circuits to modern software applications.
A hardware-specific Bruce firmware build engineered for an ESP32-S3 N8R8 development board, featuring a 1.8-inch ST7735 SPI display, 5-button tactile navigation with long-press escape logic, modular RF/NFC/GPS peripherals, and a portable Li-ion power subsystem.
Part 1 of reproducing an embedded vibration anomaly detection research system on an ESP32-S3 and MPU6050, establishing direct-register I²C validation, sensor fusion, and real-time 3D OLED visualization.
An ESP32-S3 powered 128×64 OLED video player that converts MP4 footage into 1-bit frame data and renders it frame-by-frame on an SH1106 display.
A multi-key electronic piano built entirely on a breadboard using analog electronics and the versatile 555 Timer IC.
An embedded system designed to detect gas leaks in real-time, providing both visual and audible alerts to prevent hazards.
